Title: Improvements in the manufacture of embossed rubber articles
Filed: 1933-08-23
Abstract: In the manufacture of embossed rubber articles, e.g. bathing caps, bathing shoes, &c., having surfaces ornamented with relatively high reliefs, a temporary mould carrying a forming-surface impressed with the relief negative is first coated with a surface layer of the article to be produced completely filling the impressions of the forming surface, by applying to the latter a coagulable rubber dispersion which is dilute relatively to the dispersion from which the main body of the article is to be produced, and thereafter forming said main body upon the surface layer.  In an example a mould, previously coated with a 2 per cent aqueous solution of the substance known by the Registered Trade Mark "Nekal," is dipped cold into a rubber dispersion containing from 25 to 30 per cent dry-rubber, removed therefrom, heated at 75 DEG  C. for about ten minutes, for instance by passing hot air or water through the hollow mould, and then applied to a rubber dispersion containing about 50 per cent dry-rubber for six or seven seconds; the mould is then removed and dried and the rubber films vulcanized.  In the case of a rubber glove produced as described above the initial film was 0,1 mm. thick and the second film was 0,9 mm. thick.  The two dispersions may contain vulcanizing agents, accelerators, anti-oxidants dyestuffs and fillers.  In order that its viscosity shall not be undesirably increased, the dilute dispersion should contain only a small percentage of filler.  Instead of "Nekal," water or an aqueous solution of a soap or any sulphonated fatty acid may be used as a wetting agent for the mould.  The dilute dispersion may itself contain the wetting agent.  Vulcanized dispersions may be used. The concentrated dispersion may be a heat-destabilized dispersion such as is described in Specifications 284,608, 292,964, 330,520, or 335,621, [all in Class 70].  The two dispersions may be of different colours, whereby variegated colour effects are obtained.

Title: Improvements in apparatus for bloodless measurement of the arterial blood pressure
IPC: A61B5/022
Filed: 1938-08-10
Abstract: 518,488. Recording-apparatus. KELLER, C. Aug. 10, 1938, No. 23551. [Class 106 (iv)] [Also in Group VI]  In apparatus for the measurement of arterial blood pressure in which two cuffs are employed, i.e. a central cuff nearer to the heart and a peripheral cuff more distant, the pressure oscillations in one of the cuffs are recorded as abscissae 'and those in the other as ordinates in the same graph. The desired effect may be obtained by so constructing the recording apparatus that the recording pen is actuated by the pressure in one cuff and the recording paper is moved angularly by means actuated by the pressure in the other cuff. In the apparatus shown a pressure sensitive member 1 in the form of a bourdon tube is connected at 12 to a conduit 14, which communicates by way of a socket 16 with the central cuff, and, through a connection 13, with a rubber ball or pump provided with an escape valve. To the end of the bourdon tube is attached a thread 5 which is wound round a drum 6 on a rotatable shaft 7 on which is mounted a disc 9 having a pointer 8 moving over a scale 11. The disc also carries the recording paper 10. A second pressure-sensitive device 2 is mounted in an airtight box 18 connected by a channel 19 with a three way cock 20. The interior of the device 2 communicates, through the conduit 15 with the peripheral cuff. The cock 20 in one position puts both the cuffs and the interior of the device 2 and box 18 into communication, or it may be turned to isolate the cuffs and also break connection between the device 2 and the box 18. The device 2 acts on a lever 23 fast on a spindle 22 on which is mounted a pointer 24 the end of which carries a pen 27 winch bears on the paper 10. The cuffs having been placed in position and connected at 16, 17 to the recording apparatus, the cock 20 is turned as shown in Fig. 1 and pressure is supplied to the interior of the parts 1, 2 and 18 until it approaches the systolic blood pressure. The cock is then turned to isolate the bourdon tube 1, the casing 2 and the box 18 from each other and the pressure is further increased in the bourdon tube. The escape valve of the pressure producing device is then opened whereby the recording paper 10 is slowly rotated owing to decrease of pressure in the bourdon tube, variations due to the varying pressure in the central cuff being superimposed on this motion, while at the same time the recording pen 27 oscillates under the variations of pressure proceeding from the peripheral cuff. A description of the manner of interpreting the graph produced is included in the Specification.

Title: Improvements in and relating to electrical control and indicating systems employing selsyn devices
IPC: H02K24/00
Filed: 1947-09-03
Abstract: 626,039. Dynamoelectric machines. LIVERSIDGE, J. H., and METROPOLITAN. VICKERS ELECTRICAL CO., Ltd. Sept. 3, 1947, No. 24330. [Class 35] The tooth pitches of the stator and rotor of a Selsyn are mutually fractionally different so that the mean reluctance axis is displaced through a greater angle than the movement of the Selsyn. As shown, the stator, 2 has sixteen teeth supporting a distributed winding 5 having three or more " phases," whilst the rotor 1 has eighteen teeth, the single phase exciting winding being either distributed in the stator or rotor slots or, in a modification (not shown), disposed in a single opposed pair of enlarged slots in the rotor. In order to enable further rotation of the Selsyn it is necessary to rotate the excitation axis the same mean amount as the flux movement. This is done by energizing each of a series of angularly disposed coils in turn by a switch or commutator operated by the rotation of the selsyn. In the form shown in Fig. 3, in which a commutator 10 is used, three coils A, B, C, mutually spaced 120 degrees, are energized in sequence as the commutator segments successively engage the energizing brushes 17, 18. Progressively varying energization of each coil may be arranged, e.g. by resistances controlled by the brush-span.
